TYPEWRITING MACHINE Filed July 12, 1928 Patented Mar. 11, 1930 UNITED STATES PATENT OFFICE TYPEWRITING MACHINE Application filed July 12, 1928, Serial No. 292,137, and in Cuba April 7, 1928.

This invention relates to an attachment to be used on typewriting machines, and its principal object is to hold the sheets of paper placed on the platen of the machine, thereby preventing the sheets from being blown by the Wind while typewriting, which makes the typists work bothersome and slow.

Other advantages and other considerations relative to the invention will be evident in the course of this specification, with the aid of the figures in the attached drawing, in which the same characters of reference designate the same parts in the different views.

In the drawing:

Figure 1 is a front elevation, view in detail of the attachment of the invention.

Figure 2 is a side elevation of the same.

Figure 3 is fragmentary front elevation, in detail of a portion of a typewriting machine supporting the attachment of this invention.

Figure 4 shows a view similar to Figure 3, but in operative position.

Figure 5 is a transverse, vertical, sectional view, in detail,on the line 55 of the Figure 3.

Figure 6 is another vertical sectional view, in detail, on the line 66 of the Figure 4.

Figure 7 is a fragmentary sectional view in detail, on the line 77 of the Figure 1, and,

Figure 8 is a perspective view, in detail, of the piece which holds the attachment to the body of the machine.

This attachment includes a support constituted by an elongated fiat bar 1, the upper end of which is bent at right angles and hence downwardly as indicated at 1, and projecting from the end of the same at the sides thereof are studs 2 to which are hinged the ends of a split ring 3, and which, between its ends, is formed with a yoke 3. The ends of the ring 3 are formed with notches 3 engaged by stops 4 which are extended from the side edges of the downwardly bent portion of the bar 1. To said bar 1, on the rear side and concentric with relation to the circular part of the ring 3 is attached a ring 5 made of wire.

The attachment is secured removably to the body of a typewriting machine through the medium of a staple 6 detailed in Figure 8 which is attached to the plate 7 ,usually behind the platen 8, by means of screws 9.

In Figures 3 and 5 are illustrated a sheet of paper 10 which is passedaround the platen, before typing is begun, the part of the paper not typewritten being held between the split ring 3, and retained by the stops 4 and the ring 5, which offers a SllfilClGIlt surface for resting. As the typing progresses, the typed portion of the sheet will also be held between the said plate and ring, as clearly illustrated in the Figures 4 and 6.

It is evident that within the principles of construction hereinbefore described, many modifications may be made. I therefore, do not limit myself to the above, but contemplate that changes may be made within the scope of the appended claim.

I claim:

In typewriting machines, a paper guiding attachment which comprises in combination with the platen of the machine, a support including a bar bent at its upper end; a ring of substantially circular form hinged to the bent end of the support and maintained spaced from the same by means of stops; a ring attached to the rear side of the support in concentric relation to the first mentioned ring; and means for mounting the support go behind the platen of a typewriting machine.

In testimony whereof I have signed my name to this specification.
